THOMAS BURKHARD, OF BROOKLYN, NEV YORK.

CONl-'ECTIONERS KETTLE.

SPECIFICATION forming part of Letters Patent No. 476,917, dated June 14,1892.

Application filed December 14, 1891. Serial No. 414,903. (No model.)

To all whom t may concern.-

Be it known that I, THOMAS BURKHARD, of Brooklyn, in the county of Kingsand State of New York, have invented a new and useful Improvement inCandy-Kettles, of which the following is a specification.

My invention relates to an improvement in candy-kettles in whichprovision is made for both cooking and cooling the candy.

A practical embodiment of my invention is represented in theaccompanying drawing, which shows a kettle in vertical section, with theheating or cooling coils in operative position relative thereto.

The body of the kettle is represented by A, and is provided at itsbottom with a trapdoor a., hinged to the bottom at a', and provided atits free end with a clamp-nut cand bolt c3 for closing it liquid-tight.y

lVithin the body of the kettle there are located an inner pipe-coil Band an outer pipe-` coil B', spaced from each other and from theinterior wall of the kettle. Pipes b and b', leading to the coils B andB', pass through the bottom ot' the kettle a short distance apart fromeach other, and are united outside by a connection B2. One of thepipes-b, for example-is continued and enters a cross-pipe C, provided onone side of the juncture ot the pipe l) therewith with a cock c and uponthe opposite side of said juncture with a cock c'. Pipes b and b5,communicating with the opposite ends of the coils B and B', extendthrough the side of the kettle at its upper portion and are connectedoutside of the kettle by a connection b, one ot the pipes-b4, forexamplebeing continued beyond the connection Z1 and provided with a cockc2, and the connection h6, being continued beyond its juncture with thepipe b, is provided with a cock In addition to the coils within thekettle A, I further provide the kettle with an exterior coil B2, locatedin proximity to the outer surface of the body of the kettle andconveniently held in position by means of straps D, riveted or bolted tothe kettle, as at d, at points intermediate of the winds of the coil andlooped around the winds. The straps D may be continued from the top tothe bottom of the coil,

as represented `at the right of the body of the kettle in the drawing,or they may be made to embrace the winds at intervals from the top tothe bottom of the coil, as represented at the left of the body of thekettle in the drawing. The exterior coil B2 communicates at its lowerend with a connection b2 and at its upper end with a connection o6. Theconnection b2, common to the pipes of the three coils, is provided witha petcock c4.

In operation, when it is desired to cook the candy within the kettle thecocks c, c2, and cl are closed and the cocks c and c3 are opened. Steamentering` through the cock c3 or the pipe in which it is located willpass through the connection b into the three coils B, B', and B2, andthence through the connection b2 into the cross-pipe O and out throughthe exhaust-cock c or pipe in which it is seated. When it is desired tocool the candy within the kettle, the cocks c and c3 are closed and thelcocks c and c2 opened. Tater entering through the cock cor the pipe inwhich it is located will pass upwardly through the three coils andescape through the cock c2 or pipe in which it is located. The cock c4may be utilized at any time as a drain-cock.

By the above arrangement of pipes I am enabled to quickly cook a body otcandy and as quickly cause it to congeal, the transition from cooking tocooling being eltected by a simple turning of the cocks.

What I claim isy The combination, with the bodyof the kettle, of aplurality ot series ot pipe-coils, one

of said series extending upwardly and downwardly within the body ot thekettle and another o said series extending upwardly and downwardly alongthe exterior of the kettle and in proximity thereto, exteriorconnectionscommon to the interior and exterior seri-es of coils, and cocks forregulating the transmission of hot and cold mediums at pleasure throughthe coils, substantially as set forth.
